MWS 906 CP

Multi-Channel Gas Warning System

MWS 906 CP

Application

The multi-channel gas warning equipment MWS 906 CP continuously monitors the ambient air and issues an early warning of gases and vapours that are dangerous to health, or when there is a danger of explosion, for noncombustible gases and vapours. In conjunction with the ADOS TOX 592 CO gas measurement sensor, the MWS 906 CP satisfies all requirements of the VDI-guideline 2053.

 

Fields of Application

Monitoring of:

  • Heating systems
  • Garages and tunnels
  • Liquid gas storage plants
  • Laboratories
  • Cold-storage depots
  • Plastic processing workshops
  • Chemical industries
  • Paint varnish manufacturers
  • Concentration measurement of O2
  • and many more
 

Features

  • 6-section keyboard and backlit 4-line LC-display for displaying actual values, half-hourly average values and fault messages in cleartext
  • Ready for operation, fault and gas warning indicators
  • Menu-assisted adjustment of equipment parameters via 6-section keyboard
  • Two monitoring areas (levels)
  • Five alarm thresholds for each sensor, independently adjustable from 5-100% of the measurement range, also possible to from half-hourly average values
  • 8 floating outputs for driving additional warning and control devices
  • Floating change-over contact for sirens and warning banners for each level
  • Serial output RS 232, for connecting a printer or PC
  • 4-20 mA current interface as output signal
  • Plastic, wall-mounting housing (IP 54)
  • High degree of service reliability
  • Low power consumption
  • Easy installation
  • Un-interruptible power supply (UPS) can be used
